Evaluate |4x-4(x+1)|=4

$| 4 x - 4 (x + 1) | = 4$

Simplify $| 4 x - 4 (x + 1) |$ .

Simplify each term.

Apply the distributive property.

$| 4 x - 4 x - 4 \cdot 1 | = 4$

Multiply $- 4$ by $1$ .

$| 4 x - 4 x - 4 | = 4$

Simplify by adding terms.

Subtract $4 x$ from $4 x$ .

$| 0 - 4 | = 4$

Subtract $4$ from $0$ .

$| - 4 | = 4$

The absolute value is the distance between a number and zero. The distance between $- 4$ and $0$ is $4$ .

$4 = 4$
